If you are to search the amp draw on a dishwasher or washing machine it says the draw is 10-15 amp. And presume this is an average per cycle.
Is the pic below acceptable, is this normal, this was a 30 degree clothes wash of 65 minutes long, and presume the 90a draw I’d the hot water heating. If this is the acceptable outcome, how do I prevent the cables to the load getting warm? Really appreciate any support as always worried with 15.9kw of lithium
You are confusing the amp draw on the ac load with that on the dc load. A dishwasher or washing machine will typically draw 10-15 A AT 230 V, so power = 230 V x 10 A = 2,300 W (2.3 kW). Now your 24V batteries will be providing this power to the inverter, plus some losses. Lets say the power required is 2,500 W to allow for 200 W of conversion losses in the inverter.
The battery voltage is 26 V, so the current drawn from the batteries is 2500 W / 26 A = 96A
This agrees with your SmartShunt.
How do you stop the wires heating up. Hopefully you followed the manual for your inverter and your cables are large enough to support these currents.

Thank you really appreciate response, you have made things clearer, making sense now confusing ac/dc, and will recheck my wiring
Many years ago I disconnected the hot water option on the washing machine.
The wife is now well OK with only using cold water… for the washing machine.
